This is what my gulpfile.js looks like.

var gulp = require('gulp'),
  extractTranslate = require('gulp-angular-translate-extractor');


    gulp.task('i18n', function () {
      var i18ndest = './assets/translations';
      return gulp.src([
          '!../shared/skyline/**/*.tpl.html',
          '!../shared/skyline/**/*.js',
          '!../shared/openstackService/**/*.js',
          '../shared/**/*.tpl.html',
          '../shared/**/*.js',
          './src/**/*.tpl.html',
          './src/**/*.js',
          './lib/**/*.tpl.html',
          './lib/**/*.js'
        ])
        .pipe(extractTranslate({
          defaultLang: 'en.i18n',
          lang: ['en.i18n', 'ru.i18n'],
          dest: i18ndest,
          safeMode: false, // do not delete old translations
          stringifyOptions: true // force json to be sorted
        }))
        .pipe(gulp.dest(i18ndest));
    });

This is a build manual for frontend/admin

cd <project-dir>/frontend/admin
    npm install
    npm run install
    npm run compile
    The last command creates 'bin' folder with compiled and minified admin frontend.

    npm run dev
    The command places built code inside a build folder, start local web server with livereload and watchers to rebuild app on files changes.

    npm run i18n
    The command extracts all translations keys for angular translate and place them to admin/src/assets/translations

    npm run test
    The command runs karma tests

and this is the build manual for frontend/lk

 cd <project-dir>/frontend/admin
    npm install
    npm run install
    npm run build
    The last command creates 'bin' folder with compiled and minified admin frontend.

    npm run dev
    The command places built code inside a build folder, start local web server with livereload and watchers to rebuild app on files changes.

    npm run i18n
    The command extracts all translations keys for angular translate and place them to admin/src/assets/translations

    npm run test

The command runs karma tests

How can i fix the [20:47:43] Task 'build' is not in your gulpfile Error?

Need your help. Thanks.

To answer your question: when you run gulp x, your gulpfile.js has to include

gulp.task('x' ... );

In your case, you could run gulp i18n, which would run the task named i18n or you could rename the i18n task to build and then run gulp build.

Note there are a bunch of things going on here. To start with, it looks like you haven't initialized your package.json - that's what the
